Title:
Kalman Filter Based Estimation of Decay Time for a Multimode Optical Cavity
Abstract:
We develop an extended Kalman filter to estimate the ring-down time of
a multimode Fabry-Perot optical cavity with a pulse train input. First the
extended Kalman filter is applied to data generated from a simulator to
show that the estimate of the filter converges to the expected value of
the ring-down time. It is also shown that the multimode filter improves
the estimation performance, compared to a simplified filter designed
from a single-mode model. Then the filter is applied to a set of
experimentally obtained output intensity data.
